LUBnicAfr-ING MEANS,

Application filed March '18, 19.25, Serial No. 16,434, and in .Canada March 21, 192e.

This invention relates to improvements in lubricating means and more particularly for the rotary valve .of .canning apparatus, one object of the. invention being' to provide a traveling vlubricator to wipe and lubricatel the 'outer bearing surface off rotary valve in canning apparatus.

A further object is to so.: construct the lubricator that the continuously revolving can cap feed lever of a canning apparatus may be utilized toV carry said lubricator.

lVith these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings;

Figure 1 is a view partly in section illustrating an application of my improvements, and l Y Figure 2 is an enlarged sectional view partly in elevation.

In my copending applications Serial Nos. V582,712 and 7 34,225, is shown and described, ymechanism for sealing caps to cans, for feeding caps to the sealing chamber and for discharging sealed cans from the sealing,- the cap feeding and can discharging mechanism including a rotary valve and the cap feeding means also including a revolvingV lever for moving can caps from a source of supply to said valve. My present invention contemplates lubricating means for said valve, and in the present instance the cap feed lever carries lubricating means.

In Figure 1 of the drawing is shown a portion of a cansealing chamber 1, in which is located sealing mechanism, fragments of which are indicated al' 2; a casing 3 for a valve t is located adjacent to and connected with the casing of the sealing chamber and between the valve and sealing chambers, a bushing 5 is provided for the valve, and a revolving feed lever is shown at 6 for feeding caps from a cap magazine 7 ,-all of which mechanism as thus generally described being shown and described in my A'cop/ending applications hereinbefore identilied; In the present instance, however, a bridge 7 t is provided, as shown in Figure 1, for guiding and supporting the caps as they pass from the valve 4 to the sealing lever 6 is carried and revolved by a shaft' 8 to which power may be applied: in any suitable manner. The lever 6 is provided with a frame 9 which includes Va block or enlargement 10 having a recess 11. The block or enlargement 10 is embraced by the flangedl portions 12--13 of a holder 14;*having a vertical socket 15 forming, a seat in which a felt wiper 16 is Secured; The upper portion of the back walll ofthe socket or seat is provided with a groove 17; to receive lubricant to be fed to the felt wiper and the freevertical edge of the latter is prcvided with a groove 18 tov prevent the wiper from becoming clogged, The holder 14 is pr@A vided with a central enlargement 19 and an elongated hole 20. A spring 21 seated in the recess 11 bears against the enlargement 19 and serves to press the holder and wiper forwardly,-the movements of the latter beinglimited by a pin or bolt 22 carried by the frame 9 and passing through the elongated hole 20.

The upper end of the shaft S is provided with a threaded nipple 23 to receive and support a lubricant well or receptacle l24 and the latter communicates with a hori- Zontal pipe or duct 25 carried by the frame 9. This pipe or duct extends over the upper end of the wiper 16 and discharges at its free end at the upper end portion of thc feed duct 18 in the free edge portion of the wiper. The pipe or duct 25 is also provided with a part 26 which discharges into the upper end of the lubricant duct or passage-- way 17 in rear of the rear edge of the wiper.

It will be seen that as the lever 6 revolves with the shaft 8, the wiper 16 of the lubricating device will wipe the outer bearing surface of the valve 4 and lubricate the same.

If desired, the upper and lower portions of the valve, aboveI and below those portions engaged by the wiper, may be lubricated by separate lubrcators 27, 28.

Various changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not vvish to restrict myself to the precise details herein set forth.

Having fully described my invention What I claim as new and desire to secure by Letters-Patent, is

l. In apparatus of the character described, the combination ivith a valve, ot a revoluble lubrieator having a Wiper, said lubricator being positioned to wipe and lubricate the outer bearing face of the valve during the rotation of said valve and the revolution of the lubricator.

2. The combination With a revoluble frame, of a holder having sliding connec tion therewith, a Wiper carried by said holder, and means for supplying lubricant to said Wiper.

3. The combination ivith a revoluble lever, and a frame carried thereby. of a holder having sliding connection vvith said frame, ay Wiper carried b v said trame, a spring tending to press said holder outwardly, and means to supply lubricant to said vviper.

1l. The combination vvith a rotatable frame, of a flanged holder embracing a portion of said frame and movable thereon, a Wiper carried by said holder, a spring tending to press said holder outwardly, and means to supply lubricant to said Wiper.

5. The combination vvith a rotatable frame, ot a flanged holder embracing a por` tion of said frame and movable thereon, .1 vviper carried by said holder, a spring tending to press said holder outwardly, limiting means 'tor said holder and the vviper carried thereby, and means to supply lubricant` to said Wiper.

6. The combination of a revoluble traine, a holder carried therebvv and having a seat provided With a lubricant groove, a wiper in said seat in front of said groove, a lubricant Well, and a. duct communicating with said ivell and having a part communicating with said lubricant groove.

7. The combination of a revoluble trame, a holder carried thereby, a Wiper carried by said holder, and having a groove in its tree edge, a lubricant vvell, and a duct coinmunicating 'vvith said lubricant vfell and extending over the upper end ot said iviper, said duct having an opening to discharge into the groove in the free edge of the vviper.

8. The combination with a revoluble shaft and a Jframe carried thereby, ot a yielding` holder carried by said frame, said holder having a seat, a Wiper in said seat, a lubricant vvell carried by the shaft. and a duct communicating With said vvell anil adapted to conduct lubricant to said wiper.

In testimony whereof, I have signed this specitication,
